It would be very difficult to determine since the coyote diet is very varied, they'll eat almost anything. BTW coyotes in the NW weigh twice as much as those in the SW .A 60-70 lb coyote is common in NY. They also hunt differently depending on the prey. Small game they hunt alone , large game like deer they hunt in packs. I've heard that a mountain lion requires a deer about every 10 days .
